Energy self-sufficiency redefined
Battery storage systems are currently on everyone’s lips, and for good reason. They are seen as the crucial piece of the puzzle for the energy transition: after all, it is only through efficient storage that solar power becomes available when it is really needed: in the evening, at night or when the sky is overcast. We are delighted to add the Hoymiles HiOne to our range – an all-in-one solution that, like our solar solutions, delivers top-class results in terms of flexibility, design and installation.
Until now, planners and homeowners have often faced a challenge: installing storage systems was complex, space-consuming and required the laborious coordination of various components. The Hoymiles HiOne clears away these hurdles.
Technical highlights at a glance
The HiOne combines impressive performance figures and maximum robustness into a complete package that is unique on the market. See the benefits for yourself:
- Power ratings: Hybrid inverters from 8 kW to 20 kW.
- Modular storage: 8-kWh battery modules, scalable from 8 kWh up to 64 kWh.
- MPP tracker: Up to 4 MPPTs (from 12 kW) for maximum yields on complex roofs.
- Each battery unit has its own BMS and MPPT. This means no balancing is required during commissioning and battery capacity can be expanded at any time.
- Switchover time: True 0-ms UPS function (seamless power supply during a power cut – for the whole house).
- Lifespan: High-quality 314-Ah LFP cells for over 8,000 cycles.
- Space requirements: Compact footprint of just 0.2 m² and 62 cm wall depth.
- Protection class: IP66 certified for indoor and outdoor installation.
All-in-One: Compactness meets high performance
The HiOne is a true powerhouse in a compact package. In an elegant ‘tower’ design, the system combines the hybrid inverter, the energy management system (EMS) and the battery modules. Thanks to its extremely narrow width of just 62 cm, the system fits easily even in tight utility rooms or garages.
The revolution in retrofitting
A major advantage for the longevity of your investment is the integrated DC/DC converter in each battery module. This means that new batteries can be easily added even years later, without them having to match the existing modules exactly in terms of age or state of charge. Manual, time-consuming balancing of the modules is completely eliminated.
Installation in record time
Time is a precious commodity on a construction site. The HiOne has been designed according to the plug-and-play principle. The cable-free design of the battery modules allows for easy connection. All the cabling is concealed behind a discreet side panel, which not only speeds up installation but also ensures a tidy, modern aesthetic, in keeping with the architectural standards of Megasol modules on the roof.
Conclusion: The Hoymiles HiOne is more than just a battery. It is the intelligent control centre for modern energy independence, combining Swiss standards of aesthetics and robustness with pioneering technology.
